Understanding Virtual Private Networks and its Type

One of the most innovative networking technology is VPN or the Virtual Private Networks. This technology has made node to node communication secure upto certain extent. Well, for those who are not aware of the term VPN, Virtual Private networks are a set of internet connected computers in which the communication between nodes is secure. When you connect to the internet through a dial up modem or when you access the internet at public places like railway, bus station or a hotel through WiFi, your privacy can be at a stake as the connection is not secure i.e the data you’re transmitting (your user name, password or any files that you’ll upload) hasn’t been encrypted. If you’re an employee of some XYZ company and if you’re accessing internet through a non secure WiFi to send a high secret data copy attachment via an email, you can be in a serious trouble if the mail has been eavesdropped. In this scenario, VPN’s can be immensely useful. All you’ll have to do log into a VPN client application or a website that your service provider may have shared with you. Your login is successful, you computer will share the trusted keys with a server located at a distant location. When 2 computers have established themselves trusted, the secure and encrypted communication now takes place. Now the user can do whatever office tasks he wants to do with his laptop at any public place. There are now no chances of eavesdropping taking place. Well, VPN’s are not only useful for professionals, they can be used even by students, or a normal internet user who wants to browse the internet in a secure manner. Now, as you’ve understood the benefits and advantages of VPN’s, lets see the most popular type of Virtual Private Networks- The Cloud VPN. For businesses or people who use cloud computing services, such type of service can keep the communication between the cloud servers and the users PC highly secure. Thus, as cloud computing is the future, cloud virtual private networks is the cheapest way to stay secure from eavesdropping when you’re storing data to a PC who’s location is not known to you.
